Each box contains an element's atomic number, atomic mass, name and symbol.2. The element boxes are arranged in a table of 7 rows and 18 columns.3. The columns are called groups and represent elements that have similar chemical properties due to the same number of electrons in their last shell.4. The rows are called periods. Elements in a row are arranged by increasing atomic number.5. The period number is the number of the electron shell that elements of that period are filling. Elements of a row have different chemical properties.First Three Rows of the Periodic Table(Main Group Elements)CarbonAtomic Number(No. of protons)SymbolElement nameElectronsin 1st shell*in 2nd shell**A circle around the number means theshell is full.LithiumLiBerylliumBeMagnesiumMgHydrogenSodiumNaHeliumHeBoronNitrogenOxygenFluorineNeonNeAluminumAlSiliconSiPhosphorusSulfurChlorineClArgonArGroup 1A2A3A4A5A6A7AGroup 8A protons + neutronsAtomic Mass10 p+10 n03rd electron shell1st electron shell2nd electron shellnucleuse-Shell Max. e- 1st2nd3rd11 p+12 n0Electron shells arefilled from 1st shelloutwards.Atomic Structure DiagramsAtomic Guide
